Water Supplies

Southern California imports nearly half of its drinking water supplies to satisfy the water needs of our communities. Locally, the southeast Los Angeles County relies on imported water supplies, local groundwater supplies, and recycled water. Central Basin plays a key role in delivering both imported and recycled water supplies.

One of the main goals of the District is to partner with retailer water agencies to provide regional water reliability by conducting regional planning to ensure water demands and supplies are balanced; representing the region's water interests; increasing recycled water; and expanding water conservation.

For the latest information on Central Basin's water supply initiatives, we encourage you to attend the Water Resources Committee. For information on Water Rates, visit our Finance Page.

Retail Water Providers

Central Basin provides water to 1.7 million residents from 24 cities and portions of the cities of Carson, Compton, Long Beach and Monterey Park. Additionally, Central Basin services six unincorporated areas of Los Angeles County, including East Los Angeles, Florence-Graham, Walnut Park, Willowbrook, West-Whittier-Los Nietos and South Whittier.

The District is able to service such a large population by working with 40 retail water providers and one water wholesaler. Central Basin provides your local water provider with imported water and the local retailers provide water directly to you.

In an effort to keep local water providers engaged in water issues, Central Basin hosts a monthly Purveyors Workshop. To view the calendar, please click here.
